There are other benefits of NAT, besides address range. Putting devices behind a NAT is hugely beneficial for privacy and security.
NAT is not a security feature. Your firewall blocks incoming traffic, not NAT. It introduces new complexity that now needs to be solved.
In corpo environments you have to struggle with NAT traversal for VoIP communication.
In home networks "smart" devices attempt to solve it with shit like uPnP and suddenly you get bigger holes in your network security than before. You could find countless home network printers on shodan because of this. Even though (or maybe because) they were "behind" NAT.
IPv6 has temporary IPs for privacy reasons. NAT is NOT a firewall. Setting up a real firewall is more secure and gives you more control without things like UPNP and NAT-PMP.
